Domestic Solar Installations
Solar modules generate electricity from the sun, converting radiant
energy into an electrical current. They can be used to charge batteries, as
in the stand-alone systems used to power equipment in remote places, or
can be connected into a property's main electrical supply.
Most domestic properties are connected into the property's mains electrical supply.
During the hours of daylight solar panels convert radiant energy into electrical energy. This is passed to a DC/AC inverter which creates a constant 230v 50HZ output and synchronises this with the mains supply. The locally generated power is connected to the building's consumer unit and at times when demand is modest will supply power to household appliances. At times of greater demand or during darkness the balance of power is drawn from the grid.
As a rough guide, solar panels mounted on an unshaded south facing roof will generate about 120 units of electricity (kWh) per square metre per year.
A 1kWh system will have an area of approximately seven square metres, which would produce in the region of 800 kWh a year. It should be noted that for safety reasons the inverter automatically switches off if the mains fails. It is not, therefore, a standby power system.
